WALL mom.

Application filed November 16, 1925, Serial 1T0. 69,432.

of the first section, completely around the building, and this continueduntil the full height of the building has been reached.

Another object is to provide novel supporting means for the mold forms,and particularly constructed and arranged mold forms, which can bequickly and easily removed from the finished wall section, and elevatedinto position for the next higher section.

A still further object is to provide a building apparatus which iscapable of being elevated and supported on the finished portion of thewalls of a building, so that buildings of different heights may bemolded.

A still further object is to provide a scaffolding for supporting themold forms which, when the building walls have been finished, .isadapted to be taken apart and used for the interior woodwork of thebuilding, thereby obviating-any waste of mate rials. Other objects andadvantages will be apparent from thefollowing description when taken inconnection with the accompanying drawings:

In the drawings:

Figure 1 is a perspective view of a portion of the structure used inmolding the walls of a building, and showing the manner of suspendingthe mold forms on the upri hts.

liigure 2 is an enlarged vertical sectional view on the line 22 ofFigure 1.

Figure 3 is a detail view showing the footing and the means forretaining the lower ends of the uprights.

Figure 4 is a plan view of a finished section of a corner, showing thereinforcement placed thereon, which is to be embedded between thissection and the next section moldthe numeral 20. Eac

prises a wooden bass 21, to one face of which,

ner of a building, showing the mold forms used for forming a pilaster.

In the practice of the'invention, as shown in the drawings, I firstmold-a footing 10, of cement, in the ground, on which to erect the wallsof the building, such footing being of considerably greater width thanthe thiclgness of the wall. Inside and outside mold forms 11 are used tomold this footing,

.and after the footing has been completed, I erect uprights 12 and 13 onthis footing,

adjacent the inner and outer faces thereof. Stakes 14 are driven intothe ound outwardly of the inside and outsi e forms, to hold the forms in 'place when the cement is poured therebetween. I then place boards 15across thefooting, the forms, and the stakes, and secure them by meansof nails, the inner ends of said boards engaging against'the inner andouteruprights 12 and 13, to prevent lateral movement thereof, on

the footing. The uprights are held in proper spaced relation by theconnecting braces 16, such positions being respectfully inward andoutward of the finished wall. I then stand the inetal posts 17 againstthe inner vertical faces of the inner and outer uprights, said postshaving arms 18 pivotally connected thereto, adjacent the upper and lowerends, respectively. The outer ends of the arms are pivotally connectedto vertical battens 19, which are secured to the rear or outer faces ofthe mold forms, re resented as a whole by ll of theforms 20 comissecured a metal sheet 22, which sheet is adapted to be placed againstthe cement of the wall. Secured around'the edges of the wooden base, incovering relation to the edges of the metal sheet, is an angle ironframe 23, the edge of one wing of which.

projects across the face of the base for a purpose which will presentlyappear herein.

On the upper end of each of the posts 17 is an outwardly extending arm24, and pivotally suspended on the outer end of the arm is a hook member25 which is arranged to engage with the said edge of the angle frame, tohold the same in elevated position, away from the finished wall, andwhile the form is being moved to its new position.

In normal working position the forms 20 are held in spaced arallelrelation to the posts 17 to receive t e cement thereagainst,

whereby to form the inner and outer faces of the finished wall. Thelower end of each of the posts is turned outwardly and upwardly, andflattened, to rovide a sup rt for the lower arm 18, suc arm being eld ina slightly upwardly inclined position, whereby to more readily permitthe form 20 being elevated. I

In the upper end of each of the posts 17 there is formed an opening 26,in which s engaged an arm of a member 27,sa1d member being engagedaround the upright and provided with a oint 28 which bites lnto theupright to hold the post, and the form 20 suspended thereon. his isespecially useful, when a section of the wall has been completed, andthe forms 20 are elevated into osition, thereabove, for receivingcement,

or forming the next wall section. This is continued until the fullheight of the wall is reached.

When a wall section is completed the forms 20 are swung upwardly and enaged with the hooks 25, after which the mol s are moved upwardly intotheir new positions, the members 27 sliding upwardly on the uprights,and the points 28 permitted to bite into the u rights, whereby toproperly suspend the orms in position.

In molding the sections of the walls, the

window and door frames are placed in their proper positions, and thecement poured between the forms 20, and between such frames, wherebysaid frames will be firmly molded in the walls.

Disposed vertically and centrally between the forms 20, and extendinglongitudnally thereof, is the removable core member 29, which serves toform an air space within the wall, thus dividing the wall into twoparts. To tie these parts of the wall together I place on top of each ofthe sections, as it is molded, a reinforcement 30, shown in the drawingas comprising iarallel bars 31, and transversely extending arsconnecting the bars 31 at regularly spaced intervals. The core membercomprises two spaced forms 32, each having an inclined lug 33 in theinner face of its lower end, and having its upper end secured to a metalplate 34:. A rod 35 is disposed through the said plate, and down wardlybetween the forms where it is provided with a wedge point 36 forengagement with the lugs 33 to s read the plates or forms, whereby toren or them parallel so as to properly form the air space between thewall portions. Upon pulling" upwardly 011 this rod, the forms 32 willcollapse, or moved inwardly toward each other, thus permitting easyremoval from within the wall.

The upper and lower ends of the battens 19 are 1' need in thickness andsecured between the angle frame 23 and the base 21. An intermediatebatten 37, of greater thick ness than the battens 19 is secured to therear side forms for the wider faces of the pilaster.

Short angle plates 37 are arranged to extend between the ends of themain forms 20 to the short forms 20', to reduce the narrower faces ofthe pilaster. o prevent the angle plates 37 from movin outwardly, whenthe cement is being tampe I removably secure, in embracing relation tothe ends of the main forms 20, the clamps 38', against which the saidangle plates bear.

These clamps are also adapted to be used with the main forms 20, where aform projects beyond the adjacent wall of the corner of the building,whereby to hold the forms from disengagement, while tamping.

What is claimed is:

1. A wall mold including posts, a mold form pivotally connected to andextending between the posts for swinging movement toward and awaytherefrom, the mold form having a facing secured thereto and extend ingrearwardly thereof, means on the posts for engagement with the rearwardlextending facing for supporting the mol form in juxtaposition to tieposts, and means for suspending the posts on a support.

2. A wall mold including posts, a mold form including a base, a metalfacing secured thereto and having its mar inal edges extended around therear of the use, transverse battens on the rear of the base, linkspivotally connected to the battens and posts, hooks carried by the postsfor engagement with the rear edges of the said facing for supporting theform in juxta osition to the posts, and means on the posts or suspendingthe same on asup ort.

3. A wall mol ing apparatus including spaced uprights, posts verticallyadjustable on the uprights, and mold forms including spaced walls, linkspivotally connecting the forms with the posts, means carried by theposts for biting engagement with the upri hts whereby to permit verticaladjustment 0' the posts on the uprights, and means on the posts forengagement with the form walls for suspending said walls in non-moldingposition.

11 testimony whereof, I aflix my signature.
